Benefits of technology

The patent describes methods for producing linear alkylbenzene, paraffin, and olefin products from natural oil and kerosene. These methods involve combining the natural oil and kerosene feeds, deoxygenating the oil, fractionating the combined stream to remove paraffins, and either removing or dehydrogenating the paraffins that are heavier than a specific range. The methods also include alkylating the olefins with benzene to create alkylbenzenes. The technical effects of this patent include a more efficient process for producing linear petrochemicals from natural resources.

Problems solved by technology

While detergents made utilizing linear alkylbenzene-, paraffin-, and olefin-based surfactants are biodegradable, processes for creating linear alkylbenzenes, paraffins, and olefins are not based on renewable sources.

Embodiment Construction

[0013]The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.

[0014]Various embodiments contemplated herein relate to methods for producing a linear alkylbenzene, paraffin, or olefin product from natural oils and kerosene. It will be appreciated that embodiments of the present disclosure allow for increased use of the C10 content in the kerosene feed. As will be appreciated by those having ordinary skill in the art, only a certain percentage of C10 (generally about 10% to about 15%) is allowed to be included in a linear alkylbenzene product for use in detergents. Traditionally, where only kerosene was used as a feedstock, any C10 present in an amount beyond this maximum needed to be removed from the system and discarded or put to use for the production...

Abstract

A method for producing a linear paraffin product from natural oil and kerosene includes providing a first feed stream comprising kerosene, pre-fractionating the first feed stream to produce a heart cut paraffin stream comprising paraffins in a heart cut range, and combining the heart cut paraffin stream with a second feed stream comprising natural oil to form a combined stream. The method further includes deoxygenating the natural oil and fractionating the combined stream to remove paraffins that are heavier than the heart cut range.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to methods for producing renewable detergent compounds, and more particularly relates to methods for producing linear alkylbenzenes, paraffins, and olefins from natural oils and kerosene.BACKGROUND OF THE INVENTION[0002]While detergents made utilizing linear alkylbenzene-, paraffin-, and olefin-based surfactants are biodegradable, processes for creating linear alkylbenzenes, paraffins, and olefins are not based on renewable sources. Specifically, linear alkylbenzenes, paraffins, and olefins are traditionally produced from kerosene extracted from the earth. Due to the growing environmental concerns over fossil fuel extraction and economic concerns over exhausting fossil fuel deposits, there is a demand for incorporating alternate feed sources with the traditional kerosene feed source for producing biodegradable surfactants for use in detergents and in other industries.[0003]Accordingly, it is desirable to provide met...
